Zurcon® Dualseal is an excellent alternative to an O-Ring and Back-up Ring combination. The advantages are its resistance to twisting, stability at pulsating pressures and low risk of contamination. Dualseal is easy to install and has a long service life.
In current hydraulic cylinder design, O-Ring or ORing/Backup Ring combinations are mainly used as static seals. However, this sealing solution hides the risk that during assembly the O-Ring may become twisted and that the position of the Back-up Ring is not optimal.
This solution also exhibits weaknesses with regard to pressure pulsation and the ingress of dirt. The Dualseal as a single component static hydraulic seal offers a good alternative in such cases. The Dualseal allows general use in hydraulic cylinders: Fork lifts, Mobile hydraulics, Industrial hydraulics, Machine tools, Injection molding machines, Hydraulic presses, Cartridge valves.
